USSSA Baseball Bats
(175 products)USSSA baseball bats, also called travel ball bats or big barrel bats, carry the USSSA 1.15 BPF thumbprint stamp and are built for tournament baseball. They have 2 3/4" barrels and are the hottest bats a youth player can legally swing. Most travel organizations allow them; Little League and the other rec leagues do not, so confirm your league before you buy.
This is our deepest youth collection: Marucci CAT X and CAT Connect, Easton Hype Fire and Nova Lit, Victus Nox, Vandal and Vibe, Rawlings Icon and Clout AI, Axe Avenge and Strato, Mizuno, StringKing, in -5, -8, -10 and -11 and lengths from 25" junior big barrel to 32". Prices run from about $50 to $450, with last year's models in closeout USSSA bats.
Rule changes to know: most USSSA states cap 13U at -5 (BBCOR and wood also allowed), and 14U moved to BBCOR or wood starting in 2026. If your player is 13 or 14, shop BBCOR bats alongside this page.

USSSA Baseball Bats
What makes a USSSA bat different
The 1.15 BPF standard allows more trampoline effect than USA Baseball or BBCOR, and the 2 3/4" barrel is the biggest in the game. Put the two together and a USSSA bat will out-hit anything else a 10-year-old is allowed to swing. That is why travel ball uses them and why they cost what they do.
Picking a drop
- -10: the standard from 8U through 12U and where every brand puts its most sizes.
- -8: for 11U and 12U hitters who have outgrown a -10 but are not ready for -5.
- -5: the 13U bat. Most states require -5 or heavier at 13U, and it is the natural step before BBCOR.
- -11 and junior big barrel: 25" to 27" bats for coach pitch and machine pitch, 6 to 8 year olds.
One-piece, two-piece, hybrid
One-piece alloy (CAT X, Vibe, Strato) is stiff, cheap and durable, with more feedback on a mishit. Two-piece composite (Hype Fire, CAT X Composite, Nova Lit) has the biggest sweet spot and the least sting but needs a break-in. Hybrids (CAT Connect, Avenge Hybrid) pair an alloy barrel with a composite handle for a stiff barrel and a softer feel. All three are 1.15 BPF; pick by feel and budget.
Frequently asked questions
Is a USSSA bat legal in Little League? No. Little League requires the USA Baseball stamp.
Does it need a break-in? Composite barrels do, about 150 to 200 swings at moderate effort, rotating the bat a quarter turn every few hits. Alloy barrels are ready out of the wrapper.
What is the orange cap rule? Some 2017 DeMarini CF Zen bats in -8 and -10 were retooled and are only legal with an orange end cap. It does not affect any current bat.
Will my 14-year-old's USSSA bat be legal next year? For USSSA 14U play, no; the 2026 rule is BBCOR or wood. It remains legal in 13U and in any league that allows 1.15 BPF.
